The National Weather Service has issued an Extreme Heat Watch for most of the area during this period, and Connecticut has the potential to reach the warning-level criteria. Peak temperatures are expected during the afternoon hours of Thursday, July 2, 2026, and Friday, July 3, 2026, when highs are expected to reach 100 degrees and heat indices could climb up to 110 degrees each day.

Cooling centers will be available throughout Connecticut. Anyone in need of a place to get out of the heat can locate their nearest cooling center by viewing the last that will be published online at www.211ct.org or by calling 211.

Although anyone can suffer from heat-related illness, some people are at greater risk than others:

• Infants and young children are sensitive to the effects of high temperatures and rely on others to regulate their environments and provide adequate liquids.
• People 65 years of age or older may not compensate for heat stress efficiently and are less likely to sense and respond to change in temperature.
• People who are overweight may be prone to heat sickness because of their tendency to retain more body heat.
• People who overexert during work or exercise may become dehydrated and susceptible to heat sickness.
• People who are physically ill, especially those with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation, may be affected by extreme heat.

Some prevention tips to stay safe in extreme heat include:

• Keep your body temperature cool to avoid heat-related illness.
• Stay in air-conditioned buildings as much as possible. If you must be outdoors, try to limit your outdoor activity to the morning and evening. Try to rest often in shady areas so that your body has a chance to cool off.
• Find an air-conditioned location. (Call 2-1-1 for a list of cooling centers.) Do not rely on a fan as your primary cooling device.
• Avoid direct sunlight.
• Wear lightweight, light-colored clothing.
• Take cool showers or baths.
• Check on those most at-risk several times a day.
• Pets that cannot be brought indoors should be provided ready access to water and shade to keep them cool.
• Never leave pets inside of parked vehicles because temperatures can soar to life-threatening levels within minutes.

Everyone is also reminded to stay hydrated during periods of extreme heat. As we lose fluid through sweat, dehydration is common during very high temperatures. It is strongly encouraged to:

• Drink more water than usual.
• Don’t wait until you’re thirsty to drink more fluids.
• Drink two to four cups of water every hour while working or exercising outside.
• Avoid alcohol or liquids containing high amounts of sugar.
• Remind others to drink enough water.
